ings.

This invention relates to nailing-machines, and more particularly to a machine of that character adapted for securing roofing-cleats upon the roofing-timbers and for clamping the overturned edge of such a cleat upon an upwardly-projecting portion of a'section of roof-sheathing.

The invention has for its object to provide a novel structure of nail-driving plunger in connection with means for holding the nail until driven and for bending an acute angle in the cleat where it fits against the edge of the sheathing.

The invention has a further object to provide means for bending the upper portion of said cleat over a projecting portion of the sheathing, so as to connect the cleat with the sheathing simultaneously with the driving of the nail through the cleat.

A further object is to simplify the details of structure of the several parts, so as to render the same efficient in operation and economical to manufacture.

The invention consists in the construction, combination, and arrangement of parts hereinafter particularly described, and specifically defined by the appended claims.

In the drawings, Figure 1 represents a side elevation of the machine with parts broken away. Fig. 2 is a vertical section taken at one side of the plunger-rod. Fig. 3 is a crosssection on the line.3 3 of Fig. 1. Fig. 4 is a bottom plan view of the nail-holding base with the bottom plate removed. Fig. 5 is a detail vertical section similar to Fig. 2, showing the parts in position for driving the nail and clamping the cleat. Fig. 6 is a detail perspective of the nail-holding jaws and spring dissembled, and Fig. 7 is a detail perspective of the cleat used in connection with the machine.

Like letters refer to like parts in the several figures of the drawings.

The letter A designates the base-plate of the machine, from which vertical standards A project. The standards are connected at their upper end by a cross-head A and below said head with another cross head A Through apertures A and A respectively, in these heads extends a vertically-sliding plunger B, carrying at its lower end a head B, from which project nail drivers or projections B vided with a sliding cross-head B at its lower portion, which travels upon the standards A, and at its upper portion is provided with a collar 13, secured to the plunger and having a handle 13*". Between the collar B of the handle and the stationary cross-head A a spring '13 is located, which spring is compressed when the plunger is forced downward and by its expansion lifts and returns the plunger to its uppermost or raised position. The cross-heads A and A are. secured to the for instance, by pins a, passed through the cross-heads and standards. The collar B and the sliding head B are similarly secured to the reciprocating plunger by means of pins 1).

The base A is provided with'nail apertures or passages A and in the lower portion of the base recesses A are provided, in which the nail-holding devices 0 are located. These nail-holders are composed of jaws C'and C pivoted together'upon a pivot c and provided at their pivoted end with a spring 0 for holding them together or in a closed position. The jaw O is provided with a pivoting-head c, of less diameter than the jaw, and the jaw C is provided with a similar pivoting-head 0 which heads are adapted to rotate upon the pivot-pin c, which projects downward from the body of the base A. The jaws are each provided with a semicircular groove 0 having an enlarged or tapering entrance portion 0 at its upper end to permit the entrance of the head of the nail and by the The reciprocating plunger is procontact of the nail-head with the walls of the v groove to force the jaws apart and allow the nail to pass through the same. Upon the under side of the base a plate A is secured by IOO ment of the jaws upon their pivot, so as to bring the passage through the same out of coincidence with the apertures in the base A and plate A I provide a pin a secured to the base and projecting downward therefrom, and upon each of the jaws I form a semicircular groove 0 which fit about the pin a so as to prevent the lateral movement of the jaws upon the pivot, so as to throw the nailpassage in the jaws out of coincidence with the passages through the base and plate. This pin allows the jaws to move from or toward each other, but will not permit one jaw to follow the other in its swinging movement.

The plunger is provided, as shown in Fig. 1, with two nail-drivers and the base with two nail-holding devices or jaws, so that by the depression of the plunger the nail-drivers will force the nails, which willbe held by the jaws 0, through said jaws and into the object to be nailed. As soon as the pressure upon the handle is relieved the same will be returned to its raised position for further operation.

It may be stated that any suitable form of automatic nail-feeding device may be used in connection with this machine, but as the application of such devices in nailing-machines is common in the art such a feeding device has not been illustrated in this case.

Upon one side of the head B of the reciprocating plunger I secure a cleat-bender D by any suitable means-for instance, a screwthreaded bolt D, passed through the bender and into the head. The upper end of the bender next to the head is provided with a shoulder d to bear against the under side of the head and prevent vertical movement of the bender-plate.- Below this shoulder 61 I form another shoulder d, which in the downward movement of the plate will engage the upper surface of the base A and limit the movement of the plate in that direction. Below the shoulder d a shoulder d is formed, and a recess extends from said shoulder to the lower end of the bender-plate upon its side next to the base A. The lower end of the bender-plate is tapered, as at d so as to assist in the bending of the overturned end of the cleat. vertical wall upon its face next to the benderplate and is formed at its lower end upon an angle, so as to properly bend the cleat into position. v

In the operation of the device the roofingsheathing E, of tin, copper, or other suitable material, has one edge thereof upwardly bent, as at E, and adjacent to this upwardly-bent edge of the roofing-sheathing a cleat F, provided with an upwardly-extending portion F and an overturned edge F as shown in Fig. 7, is placed so that the portion F will overlap the portion E of the sheathing. The base of the nailing-machine is then placed firmly incontact with the portion F of the cleat, so as to force the angle between the portions F and The base A is provided with a r F of the cleat into contact with the angle formed by the portions E and E of the sheathin The reciprocating plunger carrying the nail-drivers is then depressed by the handle 13 and the nails driven through the cleat into the timber G of the roofing. Simultaneously with the driving of the nail the tapered end of the benderplate will engage the portion F of the cleat and bend the same firmly down upon the projecting portion E of the sheathing, so as to form a tight connection between the sheathing and the cleat, and by confining the parts of the sheathing and cleat in the recess between the plate and the base will bend the portion F of the cleat from the inclined line shown in Fig. 7 into a vertical line, as indicated in Fig. 5 or by the dotted line in Fig. 7. It will thus be seen that upon a single depression of the handle from the position shown in Fig. 2 to that shown in Fig. 5 the cleat will be nailed to the roofing and the edge of the cleat firmly engaged with the proj ecting edge of the roof-sheathing, so that the complete operation of connecting the roofsheatin g with the roofing-timber may be performed in a very convenient manner and more rapidly than with the tools ordinarily used for such purposes. This machine therefore accomplishes in a single operation work which in the previous art has required several distinct operations and tools to effect the same, and by the relation of its parts forms a more perfect and secure connection of the cleat with the sheathing than has heretofore been effected.

WVhile I have illustrated two nail-drivers and two nail-holders embodied in the machine, it is obvious that a single one may be used or more than two applied, as found desirable in the use of the machine. It is further obvious that the details of construction neously with the driving of the nail, substantially as specified.
